c#操作excel

Posted 2023-04-07

利用c#导出数据到excel时，如何写代码避免excel的提示（如下图）

Application excel;
Workbook book;
Worksheet sheet;
object misValue = System.Reflection.Missing.Value;
excel = new Application();
book = excel.Workbooks.Add(misValue);
book.SaveAs(@"C:\temp\chart.xlsx");
workBook.Close();
excel.Quit();
或
book.Save();
workBook.Close();
excel.Quit();
这样试试追问

我想是一个按钮输出到excel时同时打开这个excel文件进行查看

参考技术A

附件是C#导出到Excel的类，下面是调用的例子：

public ActionResult UserRoleProperty_Excel()
       
            //添加自定义标题行；
            string[] TableHeader = "公司名称", "角色", "账号", "显示名","DC","分公司","部门","邮箱","是否冻结","冻结时间","最后一次登录时间" ;
            return new ExcelResult<C_UserRoleProperty>(UserRoleProperty_list , TableHeader, Server.UrlEncode("用户权限信息表"));
       

参考技术B 应该是有关掉提示的命令，我不知道C#怎么写的，perl是sheet->DisplayAlert=false 参考技术C 需要调用的，因为C#是调用系统中的接口来实现某些需求，固然excel也是系统自带的，所以肯定会留下一个应用接口，至于接口该怎么调用得自己查，别人告诉你的不全面，谢谢。

//设置程序运行语言

System.Globalization.CultureInfo CurrentCI = System.Threading.Thread.CurrentThread.CurrentCulture;

//创建Application

//设置是否显示警告窗体

excelApp.DisplayAlerts = false;

//设置是否显示Excel

excelApp.Visible = false;

//禁止刷新屏幕

excelApp.ScreenUpdating = false;

***获取最后一行、一列的两种方法***

//获取已用的范围数据
